88e1b97f16 Simplify handling of struct/union/class tags. 
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.

3768ad6d58 Implement more efficient Decl <-> DeclContext conversions. 
When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.

Note, though, that the isa<> check still uses an out-of-line function call.

44078b95ee Instantiate the BlockDecl in ActOnBlockStart() so we can use it as a DeclContext. 
This required changes to attach the compound statement later on (like we do for functions).

415d3d570a - Add BlockDecl AST node. 
- Modify BlockExpr to reference the BlockDecl.

This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?).

Still some follow-up work to finish this (forthcoming).

9bb286ff43 Migrate DeclStmt over to using a DeclGroup instead of a pointer to a ScopedDecl*. 
This also removes the ugly hack needed in CFG.cpp for subclassing DeclStmt to create a DeclStmt with one Decl*.

2231569f01 Add getTypeSpecStartLoc() to VarDecls and FunctionDecls. 
This is a temporary solution to help with the block rewriter (though it certainly has general utility).
Once DeclGroup's are implemented, this SourceLocation should be stored with it (since it applies to all the decls).

dc2ab1740a Add Builtins.def attribute for "can be a constant expression". 
- Enabled for builtins which are always constant expressions
   (__builtin_huge_val*, __builtin_inf*, __builtin_constant_p,
   __builtin_classify_type, __builtin___CFStringMakeConstantString).

Added Builtin::Context::isConstantExpr.
 - Currently overly simply interface which only works for builtins
   whose constantexprness does not depend on their arguments.

CallExpr::isBuiltinConstantExpr now takes an ASTContext argument.

an array.

8bafa2cf9f Internally store the body of a BlockExpr using a Stmt* instead of a CompoundStmt*, and use the getBody() method to do the appropriate checking. This both removes the type-punning warnings in Expr.cpp and also makes BlockExpr have more consistency checks against modifications to its body (via StmtIterator).
